Title: Data demodulator
Inventor: HASHIMOTO SHINJI
IPC: H04L27/22
Filed: 1990-04-06
Abstract: PURPOSE:To obtain very fast and stable convergence by varying a convergence coefficient of a carrier phase control circuit in response to a phase error. CONSTITUTION:When an output signal of a low pass filter 44 exceeds a preset value for a prescribed time or over, a switching control circuit 46 generates a switching control signal to turn on a switch 45. An output signal of the low pass filter 44 is fed to a variable coefficient device 31 and a carrier phase control circuit 15 varies the convergence coefficient in response to a phase error. The convergence coefficient from the variable coefficient device 31 is increased at a faster converging speed when a large phase error is detected and the convergence coefficient is decreased as the convergence is proceeded to avoid overshoot.

Abstract: PROBLEM TO BE SOLVED: To perform the failure diagnosis of a CCD sensor without using a bonnet signal by comparing the image data stored in a second memory for storing the content of a first memory at a prescribed timing every same address, and storing the address having no change in a third memory together with its frequency. SOLUTION: A microcomputer reads an image signal to a RAM 13, and shifts the image signal stored in the RAM 13 to a RAM 14 at a prescribed timing. The image signal stored in the RAM 13 is displayed on an indicator, and a CPU 15 compares the same address of the image data stored in the RAM 13 and RAM 14 every address to judge whether it is the image data having the same illuminance or not. Thereafter, the CPU 15 reads the address and the corresponding frequency in order of number, and when the illuminance is coincident with that from a photodetector corresponding to the same address, 1 is added to the corresponding frequency and stored in a RAM 19. It is checked whether the frequency of each address exceeds a prescribed value or not to perform a failure display.

Title: Electronic switch circuit
Inventor: ANDO TOSHIHIRO
IPC: H03K17/60
Filed: 1986-04-18
Abstract: PURPOSE:To always secure saturation of a transistor(TR) with the minimum base current despite the change of load by setting a TR whose collector and emitter are connected to each other at a part between an input and an output so that said TR is saturated with the collector-emitter voltage. CONSTITUTION:When the input voltage VIN is impressed to an input terminal 1, the output voltage VOUT obtained at an output terminal 2 is shown by an equation I, where VD2 means the anode-cathode voltage of a diode D2 and VBE3 means the base-emitter voltage of a control TRT3. Thus the voltage VOUT is dependent on the voltage VIN. While the collector-emitter voltage vCE1 of a switching TRT1 is shown by an equation II which is decided by the voltage VIN and has no relation with the load value. For instance, the collector current of the TRT1 increases when the load value is reduced together with increase of the output current IOUT. Then the voltage VCE tries to increase and the base potential of a driving TRT2 increases together with increase of the base current IB of the TRT1 since the potential of a control TRT3 drops. Then the voltage VCE is kept at a constant level.

Title: Electrostatic-breakdown protective element
Inventor: TANDO YASUHIKO
IPC: H01L21/822
Filed: 1988-04-13
Abstract: PURPOSE:To obtain electrostatic-breakdown protective characteristics without depending upon the polarity of applied charged voltage by using a planar type punch-through diode passing through the center of an element and having object structure to a surface orthogonal to a current path. CONSTITUTION:When positive charged voltage is applied to an external-signal input terminal D1, forward voltage is applied between a p<+> type diffusion layer 22 and an n<-> type epitaxial layer 18, and reverse voltage is applied between the layer 18 and a p<+> type diffusion layer 22. When the whole region of the layer 18 between the layers 22, 22' is changed into a depletion layer, when reverse voltage is brought to punch-through voltage or more, currents are made to flow through the 22' side from the layer 22. When negative charged voltage is applied to the terminal D1, forward voltage is applied between the layer 18 and the layer 22', and reverse voltage is applied between the layer 22 and the layer 18. Likewise, currents flow through the layer 22 side from the layer 22' when the whole region of the layer 18 between the layers 22, 22' is turned into the depletion layer by the reverse voltage. Since the speed of response is accel erated in either case, the electrostatic breakdown protection of an internal circuit 12 is conducted sufficiently regardless of polarity.
